DATE: February 11, 2013
SUBJECT: 2013 Street Improvement Project Nos. 13 -01 -3 & 13 -01 -4:
Horseshoe - Indian Hill and Sandy Hook Areas Public Hearing
PROPOSED MOTION
"The City Council orders the preparation of plans and specifications for the
2013 Street Improvement Project Nos. 13 -01 -3 and 13 -01 -4, Horseshoe - Indian
Hill and Sandy Hook Areas.
City Council approval requires a simple majority vote of the City Council
present."
BACKGROUND
At the September 10,2012 work session, staff reviewed with Council the
proposed 2013 Street Improvement project areas. Staff also discussed with the
Council the need to make improvements to more local streets then are currently
budgeted for in the Capital Replacment Plan.
On September 24, 2012, the City Council authorized the preparation of the
feasibility report.
On November 7, 2012, staff held an Open House for the Greenwood Shores
neighborhood; approximately 40 residents attended.
On November 14, 2012, staff held an Open House for the Horseshoe /Indian Hill
and Sandy Hook neighborhoods; approximately 40 residents attended.
On November 15, 2012, staff held an Open House for the Melody Hill
neighborhood; approximately 30 residents.
On December 10, 2012, the City Council accepted the feasibility study for the
proposed 2013 street improvements.

OVERVIEW, PURPOSE AND NEED FOR IMPROVEMENTS
Every year the City considers streets that are in poor condition to be rehabilitated or reconstructed.
For the 2013 Street Rehabilitation Project, staff is proposing to rehabilitate approximately 4.6 miles
of streets. The street segments within the proposed project were identified by the City's Pavement
Management software in conjunction with site investigations and are shown below.

The public hearing for the Greenwood Shores area was held on January 14, 2013. The public
hearing for the Melody Hill area was held on January 28, 2013.
HORSESHOE CURVE /INDIAN HILL PROJECT
AREA
The streets within this project area were constructed in
1978 and were sealcoated in 1994, 1999 and 2007.
Heavy patching of the roads took place in 2011. The
estimated PCIs presented with the feasibility study are
shown on the map. The City's pavement management
consultant surveyed Horseshoe Curve and Indian Hill
Road in November to determine the actual PCI. The
score for Horseshoe Curve was 16 and Indian Hill Road
was 13. A full depth mill and a 3" overlay is proposed.
No major storm sewer improvements are proposed with
this project area since the area is essentially fully
developed.

The watermain within this area is ductile iron pipe. There are no known watermain breaks within
this area. It is recommended to replace the bolts on the valves and some hydrants at this time.
Attaching anode bags to the watermain at every watermain excavation is also recommended.
The sanitary sewer is ABS pipe. Detailed review of the sanitary sewer televising reveals that two
sections of pipe in Horseshoe Curve and the sewer within Merry Place should be replaced due to
cracks in the pipe.
In general, resident questions /concerns related to drainage and assessments. These questions were
answered at the meeting or with follow -up correspondence.
SANDY HOOK & SANDY HOOK CIRCLE PROJECT AREA
Most of the streets in the Sandy Hook area were constructed in 1975. Sandy Hook Circle was
constructed in 1981. Sandy Hook Drive and Sandy Hook Circle were sealcoated in 2001 and
heavily patched in 2000 and 2011. Dakota Avenue and Dakota Circle were sealcoated in 1995 and
2001 and heavily patched in 2011. Cheyenne Trail was sealcoated in 1995 and heavily patched in
2001 and 2011. Despite the maintenance history in the project area, the pavement condition is still
poor with the estimated PCIs between 13 and 34.

The preliminary design that was discussed at the neighborhood meeting for Sandy Hook Circle was
a full depth mill and overlay. Since the neighborhood meeting, the soils investigation report has
been completed. Based on the soils report and onsite investigation, staff is now recommending
Sandy Hook Circle be edge milled and a 2" overlay be paved. These streets have curb and gutter

and have an adequate aggregate base section. The other areas in this neighborhood are still
recommended to have a full depth mill and overlay. This design change has also lowered the
proposed assessment amount for Sandy Hook Circle.
Due to the fully- developed condition within this area, there is little opportunity to install stormwater
management facilities within the area. Staff is planning to meet with the residents along the Sandy
Hook Road cul -de -sac and Dakota Avenue to discuss opportunities to install rain gardens. A map of
the existing storm sewer and drainage area boundaries is shown below.
The watermain within this area is ductile iron pipe. There are no documented watermain breaks. It
is recommended to replace the bolts on the valves and some hydrants at this time. Attaching anode
bags to the watermain at all excavated watermain areas is recommended.
The sanitary sewer in this area is PVC pipe. The sanitary sewer has been televised to determine if
there are any structural deficiencies and/or inflow /infiltration issues with the pipe. One section of
pipe within Dakota Avenue will be sealed with the inflow /infiltration project this year. The
remainder of the pipe is in good condition.
In general, resident questions /concerns related to drainage and assessments. These questions were
answered at the meeting or with follow -up correspondence.
PROJECT FUNDING
Special assessments to the benefitting properties are proposed to pay for a portion of the proposed
2013 Street Improvement Project No. 13 -01 per the City's assessment practice. The remaining
project costs are proposed to be paid from City funds. All the utility improvements are proposed to
be paid for by the associated utility fund. The preliminary funding for all project areas is shown
below:

As mentioned previously an edge mill and overlay is proposed for Sandy Hook Circle since the
street is newer and has curb and gutter, therefore it is proposed that the properties with access to
Sandy Hook Circle be assessed separately from the remainder of the Sandy Hook area project.
The estimated assessment for the Sandy Hook area (excluding Sandy Hook Circle) is calculated as
follows:
Total estimated street cost, Horseshoe /Indian Hill area: $375,086.44
40% of $375,086.44 is assessed: $150,034.58

Justification I
The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the
life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
Rehabilitation projects extend the life of the street. In cases with utility or poor sub grade needs to be replaced or where streets have deteriorated
to a point where rehabilitation will no longer be practical reconstruction of the street is necessary. A feasibility study is written to consider the
merits of the project and scope of work.

Justification
Me City considers the condition of the existing utilities in the process to select streets for rehabilitation in an effort to realize cost savings by
:onsolidating these projects and also to avoid potential cuts in recently improved streets. If significant repairs are necessary to the existing water
vain, replacement may be the most cost effective option. Given the highly corrosive soils in the City, water main replacement is an ongoing
)roject in the City.

Description Total Project Cost: $1,050,000
This annual project includes televising, repairs and rehabilitation of existing sanitary sewer. The program also detects and eliminates points of
entry of ground water and surface water into the City sanitary sewer system Projects have been identified from the 2006 Inflow and Infiltration
Report. The projects were reviewed by Metropolitan Council and approved in Iieu of surcharge fees.
Justification
City staff has identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage
treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its
way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to
the City for sewage disposal and increasing the load on the City's lift stations.

The efforts may decrease operational costs, MCES fees and emergency call outs. It is also the City's intent to use connection charges to help fund
for those costs. It is the City's belief that as new customers come on line those connection fees should help fund future infiltration problems.

YES NO ABSENT
Staff spoke to Eric Newton (Indian Hill Road) on the phone and he wanted the City Council to consider
his comments regarding the project. His opinion is that the road needs work, but it's the wrong time
(economically) to do the project. He also feels that the interest rate is too high.
